The hashCode() method is a built-in method of the java.nio.charset returns the computed hashcode of any given charset.
Syntax:
public final int hashCode()
Parameters: The function does not accepts any parameter.
Return Value: The function returns the computed hashcode for the charset.
Below is the implementation of the above function:
Program 1:
// Java program to demonstrate// the above functionimport java.nio.charset.Charset;import java.util.Iterator;import java.util.Map;  public class GFG {      public static void main(String[] args)    {          // Gets the charset        Charset first = Charset.forName("ISO-2022-CN");          // Prints the hash-code        System.out.println("The hash code for ISO-2022-CN is " + first.hashCode());    }} |
Output:
The hash code for ISO-2022-CN is 1450311218
Program 2:
// Java program to demonstrate// the above functionimport java.nio.charset.Charset;import java.util.Iterator;import java.util.Map;  public class GFG {      public static void main(String[] args)    {          // Gets the charset        Charset first = Charset.forName("x-windows-949");          // Prints the hash-code        System.out.println("The hash code for x-windows-949 is " + first.hashCode());    }} |
Output:
The hash code for x-windows-949 is -1698752417
